Here at Hellas Direct, we provide you with one free of charge trailer certificate for the vehicle insured with us- both under the same tax number. All you have to do is to select the option "I would like a trailer certificate" just before the checkout process of purchasing a new car insurance on our web platform (see the photo below for more details).
If the trailer has a different registration plate from the car insured, please contact us at help@hellasdirect.gr.
If you have already issued a trailer registration and have received a new licence plate, you will need to send us an email at help@hellasdirect.gr containing the issued registration, in order for us to send you the trailer certificate.
If you purchased your insurance through a comparing car insurance platform, you have to ask them for the trailer certificate.
